New Revision: 204546
URL: http://svn.freebsd.org/changeset/base/204546
Log:
MFC x86emu/x86bios emulator and make previously i386 only dpms and vesa
framebuffer driver, etc. work on FreeBSD/amd64.
A significant amount of improvements were done by jkim@ during the recent
months to make vesa(4) work better, over the initial code import. This
work is based on OpenBSD's x86emu implementation and contributed by
paradox <ddkprog yahoo com> and swell.k at gmail com.
Hopefully I have stolen all their work to 8-STABLE :)
All bugs in this commit are mine, as usual.

+.Sh NAME
+.Nm dpms
+.Nd VESA BIOS DPMS driver
+.Sh SYNOPSIS
+.Cd "device dpms"
+.Sh DESCRIPTION
+The
+.Nm
+driver uses the VESA BIOS to manage an external display during suspend and
+resume.
+When the machine suspends,
+the
+.Nm
+driver turns the external display off.
+When the machine resumes,
+it restores the display to its state when the driver was first loaded.
+.Sh SEE ALSO
+.Xr acpi_video 4
+.Sh BUGS
+.Pp
+The VESA BIOS DPMS calls do not provide any way to identify a particular
+display or adapter to manipulate.
+As a result,
+this driver may have unexpected results on systems with multiple displays
+and/or adapters.
